Though among the top players in America, Go had a hard time competing against the stronger Asian players. In the 2000 World Junior Championship Go lost in the first round, but was the best performing American player in the tournament, giving the strong Indonesian player a challenge, while other American players barely scored against weaker European players. In 2006 Go competed in many prestigious tournaments, including Japan Open, China Open, Chinese Taipei Open, Thailand Open, Macau Open, Korea Open, and the US Open. Go performed well in the US Open, making it to the quarter final.
